. zThis inventionrelates toengines'or ineehanism's employing o l for lubricating or other purposes wherein it is desirable that'provision loe made for-cleaning of the oil, for the circulating of the-oil after'cleamng to certairr parts of the mechanism as requirechfland also for the ra-is1n of the cleaned oil to elef vated parts ofthe mechanism.

'In its more particular application the invention h-as'for-it's obj ect to provide in an engine meansfor eentri fugally cleaning oil utilized in connection with the engine mechalni'smya'nd means effecting the circulation of the cleaned oil'to required. parts'of the engine mechanism and thereafter hack to the centrifuge;'the said invention still further contemplating the utilizing of the flywheel of the centrifuge insuch a systen'n 7 Still further theinvention has for. its ob- -jiectto combine anoil cleaning centrifuge with a centrifugal: pump; arranged to discharge Cl'GElILQll from the centr fuge to-requi-red parts 7 of the engine mechanism; and has as a fur- (her object the provisionv of means whereby 'therotor of the centrifuge operates .to effect 'the returrr of 011 from a well or suinpto the interior of the centrifuge; e

The invention further aims to provide a centrifuge with an annular wall determinin'g i the maximumdepth: of oil in the centrifuge and a centrifugal pump forming part of the rotor oft-he centrifu ge receiving the overflow of the centrifuge and discharging it bya suit- I able conduit vwhereby it is led. in any required direction; V

A further object of the-invention is to provide in an engine having elevated mechanism to which clean'oil is to be supplied, an oil-circulating system; having interposed thereinan 'o'il" cleaning centrifuge and a centrifugal pump operating with the; centrifuge vto r'eceive theoverfiow therefrom and directit to the elevated mechanism;

An important object of the said invention is to provide forthe centrifugal skimming of clean oil. from' a centrifuge by means of teen 'trifu gal pump forming part of: the said centrifuge structure and rotating therewith.- Still further objects or advantages subsidiary 'orin'c'id'ental to the aforesaid objects, or resulting from the construction or oneration of the invention as it may be carried into effect; will become apparent as thesaid invene tion ishereinafter furthendisclosed; i

Incarrying the said invention'into effect,

Oil to be cleaned is reeeived in' the sump 5, and, opening from the sidewall of the chflmbei 2 at a point above the lower part-of tithe" annular IiHg fifOfthG centrifuge, there is well'8 from whicha discharge pipe 9'ex tends in a downwardly inelineddirection to f the'interior ofthe fly-wheel centrifuge, so that v 1 oil entering the well 8 passes through thesa'id pipe line by gravity into the annular cham- -bei ,7 oftlie said centrifuge, the oilbeing-ele- --vated*-from the *sum'pihto the We llf 8 by the iinpelling' action of the rim ofthe flywheel.

To facilitate the 'lift iiig'ofthe'oil by the fly wheel into'tlie well=8 in therequired manner the: chamber 2 may be formed to provide a substantially Volute' passage 10 extending from tl'ie's'ump to th'e receiving'opeiiing of the'said Well 8; The arrangement described affords a simple methodof transferring oil from the sump to theinteriorof the flywheel centrifi'ige,"the operation being continuous" as long-asthe flywheel isrotating and there is oil in the sumpto becleaned. v

As the annular chamber? of the flywheel centrifuge becomes 'fill'ed with oil, overflow takes" place overthe'inner; edge of the wall 6,'this-oyerflo'w oil being'elean, and provision is madelforzireceivingthis clean overflow oil and; pumping it 'to r'equiredme'clianisms or V xlocations, the means employed being in the i form of aflcentrifugal pump which Operates as a'unit'with the flywheel centrifuge.

I "This'pump is formed by prc'ividingafur: ther wall or ring 11 spaced from the wall 6 I by spacers 12 and pi'ovidedwith an inner flange] 13 extending "into the centrifuge through the opening 'offthe said rin fi b t, .1
